SPRINKL'ER.

This invention relates to improvements in sprinklers.

It is an object of the invention to provide an vimproved sprinkler to` irrigate lawns,

gardens, and the like, which will have a movable nozzle, whereby a Astream'of waterV the member and nozzle carried thereby upon the standard.

`With the foregoing and other objects in View which will be made manifest in the following detailed description and pointed out in the appended claims, reference is had to the accompanying` drawings for an illustrative embodiment of the invention, where- 1n:

Figure 1 is a top plan view of the improved sprinkler, the extreme positions of the nozzle being indicated in dotted lines;

Fig. 2 is a vertical section taken substantially on the line 2-2 of Fig. 1; and

Fig. 3 is afront elevation of the sprinkler.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved sprinkler consists of a standard 10, which may constitute a water pipe or other similar conduit. Upon the standardv 10 a T 11 is mounted. A nipple 12 is threaded into the T above the standard 10 and Va member 13 is rotatable therein. The member 13 is provided with an enlargement 14 which pre- Y vents withdrawal of the member 13 through the nipple 12. The upper end of the member 13 is threaded into an elbow 15. A suitable, pipe section 16 is threaded into the elbow 15 and carries an elbow 17 upon which a nipple 18 is mounted.l AAnother nipple 19 is threaded into the nipple 13 anda membei 2O similar in construction to the member 13 is rotatable therein. The member 20 is provided with an enlargement 21 which prevents withdrawal of the member 20 from within the nipple 19. i

A nozzle 22 is threaded on to the upper end of the member 20. This nozzle is provided with a triangular or V-'shaped orifice, as indicated at 23. Because of the fact that the edges of the orificeadjacent the bottom are close together, the friction of the water being discharged through the orifice adjacent the bottom is greater at that point than adjacent the top `of the orifice. TheV result is that the `particles of water discharged.. through the orice adjacent its bottom are not discharged with as great a velocity as the particles ofwater discharged through the orifice adJaceiit the topthereof. This causes certainV of the drops of water to fall and `strike the ground adjacent the sprinkler as well as at a considerabledistance therefrom,

Vso that all of the ground over which the sprinkler is adapted to play is equally irrigated. An arm 24 is securedto the nozzle 22 by means of a set screw `25and is adapted to cause rotation of the nozzle 22 with respect'to the nipple 19. A bracketV 26 is secured upon the nipple 19` and has adjustable set screws 27 and 28 which are adapted to engage the arm 24 and adjustably limit its movement. n f

An elbow 29 is threaded into the T 1l and ,carries a rod30.. This rodalso supports an elbow 31 to which is secured a pipe section 32. tion 32 there is disposed va T 33, from whichv pipe sections 34 and 35 extend. The outer ends of the pipe sections 34 and 35 are bent downwardly, as indicated at 36 and 37 respectively. The down-turned portions of the pipe sections 34 and 35fprovidestops engageable by the arm 24.

The operation of the sprinkler is as follows: When water is discharged through the standard orV conduit 10, it passes upwardly Upon the forward end of the Vpipe sec-- through the member 13 through the pipe sec- Y tion 16, through theV member 2O and is discharged through the nozzle v22. When thel nozzle 22 bearsan angular relation with respect to the pipe section 16, asshown .in Fig.

1, the reaction from the discharge of watery through the nozzle exerts a force upon the i pipe section lzwhich causes the pipe section toswing toward the stop 36. The rate at which the'pipe section 16 swings depends i upon the angularity of the nozzle 22 andthe pip@ Section i6. vif the direction in whichk the water is discharged from vthe nozzle 22 is substantially perpendicular to the axis of the pipe section 16,;the movement of the allel or in line with the axis of the pipe section 16. The angular relation with which Vthe nozzle 22 may bear with respect to the pipe section 16 may be adjusted by means ot the adjustable set screws'y 27 and 28. Then the pipe section 16 swings toward the pipe section 34, the arm 24 engages the stop 36. This stops the movement of the pipe section 16 and the nozzle 22, and rotates the nozzle 22 upon the nipple 19 to assume the position indicated in dotted lines adjacent the top of Fig. 1. VByl thus rotating' the nozzle 22, Athe reaction from the discharge oi' Vwater causes the pipe section 16v and the nozzle 22 to move inan opposite direction. The arm 24 eventually engages the stop 37 and swings the nozzle 912 into its original position. ln

Vthis manner, as may be readily understood,

the nozzle is caused tooscillate over a portion of a circumference'. Obviously, the pipe sections and V may be bent so as to cause the nozzley to oscillate over any portion Vof a circumference which may be greater or Y of the invention as lessor equal to a lia-lf circle.

The member 13, elbows 15 and 17, pipe section 16 and-nipples 18f'and 19, although in reality are separate pieces, constitute a single member which is rotatable upon the standard 10*v and upon-*which a nozzle is rotatably mounted. Obviously, the arm 24 may be made integral with the nozzle 22, if desired; and also the' bracket 26 may be made integral with the nipple 19, if desired. The frame com-posed oi vthe rod 30', the'pipe section 32 and the pipe sections 34@ and 35 may be made of a single solid piece', if so desired. y

From the above it will be readily understood that an improved sprinkler is provided which mayv be easily and quickly constructed from conventional plumbers supplies.

The improved sprinkler entirelydoes 'away with gears,V whichv have sometimes hereto-fore been employed for producing cer- Vtain types of rotary sprinklers. These gears have' the disadvantage of easily and quickly y becoming worn because of small particles of sand in the water and because of the tact thatv they frequently rust. 'The improved sprinklerv is freefrom vthese disadvantagesl and has because yof its simplicity of construction a longer life than the aforementioned sprinklers provided with gears.

' It Will be understood that various changes inthe Vdetail of constructionl may be made without departing from the spirit or scope claims.

I claim:l
